Surgical complications of Ehlers-Danlos syndrome in children

The Ehlers-Danlos syndrome is a special challenge to the surgeon because of its relative infrequency and the late onset of overt symptoms, such as hyperelastic skin. We should consider this diagnosis in every child with recurrent inguinal herniae and search for its stigmata. A child with a known Ehlers-Danlos syndrome who requires an elective operation should be carefully studied for coagulation disorders. If there is a history of past injuries or operations in which there was poor healing, the benefits of the proposed operation must be carefully weighed against possible complications. Operations must be carried out with great care to avoid tearing the skin and fascia. Meticulous attention is given to hemostasis to prevent postoperative bleeding or hematomas. Inguinal hernias in these children resemble those seen in elderly patients. The transversalis fascia is thin and the internal ring is hugely dilated. An adult-type repair, with the use of mesh or felt may result in a lower incidence of recurrence. In addition, the Ehlers-Danlos syndrome may be yet another etiology for obscure gastrointestinal bleeding in children. Specific enzyme defects have been identified in 2 of the 7 subtypes of this disease. Further, biochemical study of connective tissue defects may contribute to our knowledge of normal collagen synthesis and wound healing.
